More than 2.25 billion cups of coffee are drunk throughout the world each day, and it's likely that many taste bitter. Now, a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups.
Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes biter was true. They used 36 volunteers and three different colored cups---blue, white and transparent glass--- to examine the claim.
In one experiment, the white cup increased the intensity (浓度) of the coffee taste relative to the transparent cup. Then, in a second experiment, coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups, while the blue cup made the coffee taste the sweetest.
The scientists believe that the color brown may be associated with bitterness, and coffee in a white cup appears the brownest. “Our study clearly shows that the color of a cup does influence our sense of the coffee taste,” leading author Dr George Doorn, wrote in an article for The Conversation. “The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups,” he said. “The potential effects may spell the difference between a one-time purchase and a return customer.” Actually, the idea that color can change the food and drink taste came out many years ago. A study published last year reported that red, strawberry-flavored cake served on a white plate was rated as 10 percent sweeter than the same food presented on a black plate.
1.The passage is mainly about _____.
A. the popularity of sweet coffee.
B. an experiment made in Oxford.
C. the effect of cup color on coffee's taste
D. useful tips on how to make coffee.
2. In which cup will coffee taste the sweetest?

3. Café owners should consider their cups' color in order to ______.

Do you find yourself reaching for just one more cup of coffee to get through the day? Are you tired of being tired ? Instead of relying on things like coffee or sugar for energy, get happy by eating more foods that give you energy through nourishment. Here are four foods that can help improve your energy levels.
Hemp Seed
A complete protein, rich in fiber and omega-3s, hemp is a great low-glycemic (低胰岛素) addition to any diet. The glycemic index (GI) is a measurement of how fast the carbohydrates in food are broken down into glucose (葡萄糖) and how much it will affect your blood sugar. Fiber, fat and protein all lower the GI of a food, which is why hemp seeds (along with nuts, seeds, whole grains and legumes)are low-glycemic. Look for hemp seed oil for salad dressing, and hemp seeds to be added into salads.
Soaked Almonds
Raw almonds are nutrient dense, and soaking them releases(释放) higher nutrition potential. Soaking increases vitamin levels and removes the enzyme (酶) inhibitors that slow down digestion. I soak my almonds in water overnight (at least eight hours) and then dry them.
Quinoa
It is 20-percent protein, making it a balanced source of carbohydrates. Even though you feel like you're too busy to make home-made meals, quinoa is a fast food that cooks in less than 15 minutes.
Green Tea
Caffeine from green tea feels steadier and less sharp than the spike and crash with caffeine from coffee. This is likely because green tea contains L-theanine, a kind of acid found in tea that helps promote relaxation.
1.The writer wrote the passage in order to______.
A. introduce four foods making people energetic
B. find reasons why people need some coffee
C. reach for something to get through the day
D. tell people way of keeping fit
2.Why did the almonds get soaked?
A. It helped increase the enzyme. B. It helped unlock the nutrition.
C. It helped make digestion slow. D. It helped lock nutrient dense.
3.From the fourth paragraph we can know quinoa_______.
A. is rich in protein B. includes much fiber
C. can be served quickly D. has less sharp flavor

More than one billion people currently live in environments where water is in short supply, making water one of the most highly prized natural resources. Scientists are always searching for ways to increase access to this valuable resource. They may have found a solution in an unlikely area: one of the driest places on Earth.
The Namib desert in Africa is one of the world’s driest places, while Namib beetle is a unique organism that grows in this environment because of its amazing physical adaptation. The wings on the Namib beetle are filled with bumps and grooves(槽) that help it collect water from the air. The top of each bump is smooth like glass and attracts water. But the slopes of each bump and the grooves in between the bumps have waxy (带蜡的) surfaces that repel water . Each time the fog occurs, the beetle positions its body at a 45-degree angle to the wind. As the wind pushes the fog across the desert, each bump on the beetle’s back collects water. When enough moisture has been collected from the fog, a drop rolls off the bumps into the waxy grooves and then into the mouth of the beetle.
Scientists are using the Namib beetle’s wing design as a guide for creating their own water-collection surfaces. They have inserted dozens of glass globes into thin layers of wax. Similar to the bumps and grooves on the wings of the beetle, the smooth glass bubbles collect water, while the wax repels it. By placing the glass-andwax panels in environments with high-moisture air, the scientists think they will be able to collect water.
The Namib beetle’s wing design may also provide unexpected solutions to other problems. In areas where thick fog causes chaos, panels of these water-gathering surfaces may be able to remove the fog. This could potentially reduce travel delays at airports and prevent fog-related accidents on roadways. It seems that studying this little beetle may lead to a variety of benefits for humans.
1.What will the Namib beetle do when fog appears in the desert?
A.It will release a waxy substance to cover its back.
B.It will place its body in a particular way to collect water.
C.It will create bumps and grooves on its wings.
D.It will open its mouth to drink the water in the air.
2.The author focuses on a unique feature of the Namib beetle in order to highlight how the beetle ________________.
A.could serve as a source of water for desert travelers
B.struggles to survive in the dry part of the world
C.uses its wings to stay cool in a dry environment
D.is able to get access to water in the absence of rain
3.What’s the writing purpose of this passage?
A.To prove that water can be obtained from moist air.
B.To explain how the Namib beetle adapts to living in a hostile environment.
C.To show how people can apply designs from nature to create solutions to global problems.
D.To stress that water is a valuable resource in many areas on Earth.

UNICEF is appealing for more than one billion dollars in aid for women and children around the world.The United Nations Children's Fund has released its " Humanitarian Action Report" for two thousand ten. The report lists twenty -eight countries and territories with some of the world's most pressing crisis affecting women and children.
Haiti was considered to be in crisis long before the earthquake in January.The deputy executive director of UNICEF, Hilde Johnson, says the quake has only made the need for aid more immediate.But she says children all over the world have the right to the same assistance as children everywhere else.
The "Humanitarian Action Report" discusses several issues that UNICEF says increasingly threaten the basic rights of women and children.It says climate change has caused droughts and' food insecurity in many areas.High food prices and the global financial crisis of two thousand eight - two thousand nine have only added to poverty and malnutrition ( 营养不良).And armed conflict continues to threaten the lives of millions.
Hilde Johnson says children are always the most affected by conflicts and disasters.They face an increased risk of abuse, including sexual violence and other serious rights violations (侵犯).
UNICEF deals with about two hundred emergencies around the world every year.The greatest need last year was in sub - Saharan Africa.The report says drought, food insecurity and civil unrest affected about twenty - four million people.
Violence and displacements( 驱逐)of people were especially bad in Sudan, Chad, the Democratic Republic of Congo and the Central African Republic.
In Asia, UNICEF expects its financial assistance needs to more than double this year.This is partly the result of adding Pakistan and the Philippines to the latest report.In Pakistan, it says, more than two million people have been forced from their homes by the conflict in the.Swat Valley and other areas of the northwest.And in the Philippines, more than two hundred thousand people are still living in shelters after severe storms last year.
This years UNICEF report talks about the value of public and private partnerships in helping children and families in emergencies.
And thats the VOA Special English Development Report, written by June Simms.For a link to the UNICEF report listing the twenty - eight countries and territories in crisis, go to www.unsv.com.I'm Steve Ember.

高二英语阅读理解简单题查看答案及解析
There are more species of beetles than any other form of life. About 380 000 species of beetles are known to exist, and more are discovered all the time. There are several theories about why there are so many beetles, but fossils evidence shows that beetle species die out less than other animals, Beetle species exist in such huge number because beetles are true survivors. They refuse to die out.
One of the reasons beetles survive so well is their body design. Most beetle species have two pairs of wings. The front pair of a beetle’s wings are hard and thick. They are not used for flying. These protect the back set of wings and the beetle’s stomach. Instead, some species of beetles have lost the ability to fly, but they are still equipped with front wings. The wings protect the beetle’s soft parts from harm. These features help protect beetles, which makes them less likely to die out if they are faced with new predators (捕食性动物).
Beetles can also eat a wide range of foods. Beetle species live all over the world, and they have many different types of food available to them. Most beetles are omnivores. That means they eat both plants and animals. Their mixed diets help beetles adapt to many different habitats. Over the course of time, food sources, like certain plants and animals, do not exist anymore. Others spring up. The beetle survives because it can find something to eat, no matter what.
Finally, beetles are good at moving quickly over long distance. Any change in an animal’s environment can be dangerous to it. For example, many species died out during the Ice Age, when Earth’s temperature dropped for a long time. However, some species can avoid dangerous environment changes by moving to a new place. Research shows that beetles respond quickly to shifts in temperature. They can move to safer environments.
Beetles’ bodies and habits help give them an edge over other creatures. They are unlikely to die out. As a result, beetles make up nearly one quarter of all animal species. There are more types of beetles on Earth than there are types of plants. Some types of beetles that exist today were around during the Permian period of history, 284 million years ago. Beetles, clearly, are here to stay.
1.What is important about a beetle’s front wings?
A.They are used to catch the prey.
B.They enable the beetle to fly.
C.They help the beetle move quickly.
D.They protect the soft body parts.
2.How do beetles respond to changes of habitats?
A.They are adaptable to the food change.
B.They can change their body temperature.
C.They are adaptable to the freezing cold weather.
D.They can use their wings to fight against the cold.
3.What is the most probable title of the passage?
A.The Ice Age affected the beetles
B.Different habitats affected the beetles
C.Beetles: the six-legged survivors
D.Beetles: the unique predators
